3D printing construction
3D printing construction is a technology that consists of building houses by depositing
a material (concrete for example) layer by layer. It can either involve the use of a 3D
printer attached to an arm which actively builds a project on-site or the use of
printers in a factory which create components of a building project to be assembled
later-on. House 3D printers use extrusion technology. Some construction 3D printers look
like super-sized desktop FFF/FDM 3D printers (gantry style), whereas others consist of a
rotating mechanical arm. In both cases, paste-type components such as concrete are used
as filament. The material is pushed out of a special nozzle to form layers. The printer
creates the foundations and walls of the house or building, layer by layer and the
ground is the printer’s build plate. Some concrete 3D printers, however, are used to 3D
print brick molds. When molded, the bricks are then piled atop each other manually (or
with a robotic arm)
